Ok folks - next on my to do list is the speedometer. There are really only 3 points of possible failure:
The sender gear The cable The speedo itself The old car was working when she went to sleep so I can easily swap out parts. Whats the most likely place to start? |

Does it do this all the time Dave? From what I've seen poking around the drive chain is pretty much all or nothing. I'll know better when I get the failed angle drive apart and see what caused the failure.
My best guess is that the mechanism in the meter is sticking. When the vibration/speed gets enough to break it loose then it performs normally. I haven't had one apart but I'm assuming that it is just a little generator that produces current according to rpm and drives a standard galvanometer from there. There could be a problem with the seating of the needle or something like that. If it fails every time you start it up from cold try the drill trick. If it doesn't work with the drill it would support the theory that it is the speedo itself. If it does work hook it back up and drive it. If the speedo works with the drill but not not when driving then you may be looking at the angle drive. |
